Abstract: Techniques are disclosed to add augmented reality to a sub-view of a high resolution central video feed. In various embodiments, a central video feed is received from a first camera on a first recurring basis and time-stamped position information is received from a tracking system on a second recurring basis. The central video feed is calibrated against a spatial region encompassed by the central video feed. The received time-stamped position information and a determined plurality of tiles associated with at least one frame of the central video feed are used to define a first sub-view of the central video feed. The first sub-view and a homography defining placement of augmented reality elements on the at least one frame of the central video feed are provided as output to a device configured to use the first sub-view and the homography display the first sub-view.

Abstract: A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

Abstract: A process to track and provide positional information for display on a remote device includes receiving, on a first recurring basis, time-stamped position information of participant(s) in a competition. The time-stamped position information is captured by a telemetry tracking system during the competition and describes a time-stamped position of each of one or more corresponding participants in a predetermined spatial region. The process includes communicating at least a subset of time-stamped position information to the remote device on a second recurring basis. The remote device uses the time-stamped position information to overlay a representation of one or more of said participants onto a first virtual reproduction of at least a relevant portion of the predetermined spatial region to produce and display an instance of a compiled virtual scene that shows a respective position of each of the participant(s) on the first virtual reproduction of the predetermined spatial region.

Abstract: Disclosed are systems and methods for feeding welding wire for welding-type applications. The wire-feeder system comprises a base platform, a spool hub, a drive roll assembly, and a wire guide assembly. The spool hub can be mounted to the base platform perpendicular to the base platform and configured to support a wire spool. The drive roll assembly can be mounted to the base platform, and having one or more sets of drive rollers configured to feed wire from the wire spool toward a welding torch. The wire guide assembly can be mounted to the base platform separately from both the wire spool and the drive roll assembly.

Abstract: An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor includes a controller operatively connected to the endodontic motor. The controller may include a processing unit that is configured to direct the rotation of the endodontic motor in the forward direction for a coast time and configured to direct the rotation of the endodontic motor in the reverse direction for a coast time. The forward coast time is separately calculated from the reverse coast time. A method for asymmetrically coasting a reciprocating endodontic motor includes rotating an endodontic motor in a forward direction and calculating a forward coast time for the forward direction and coasting the endodontic motor in the forward direction for the calculated forward coast time. After coasting the endodontic motor in the forward direction, the endodontic motor is rotated in a reverse direction. The reverse coast time is different than the forward coast time.

The self-leveling mechanism may include an engagement tab extending from the housing and configured to be the first aspect of the foot pedal to contact the working surface. The self-leveling mechanism may additionally or alternatively include a cord guide configured to pitch or cant the housing in a preferential direction.

Abstract: Method and apparatuses for powering medical devices on and off. One embodiment provides an apparatus that includes a plurality of medical devices. Each of the plurality of medical devices is configured to be electrically activated and deactivated. A central unit is configured to communicate with each of the plurality of medical devices and to receive a signal indicative of a triggering event. In response to receiving a signal that a first triggering event has occurred, the central unit sends each of the plurality of medical devices a signal to activate at the same time.

Abstract: An apparatus for mapping and/or ablating tissue includes a braided conductive member that that may be inverted to provide a ring-shaped surface. When a distal tip of the braided conductive member is retracted within the braided conductive member, the lack of a protrusion allows the ring-shaped surface to contact a tissue wall such as a cardiac wall. In an undeployed configuration, the braided conductive member is longitudinally extended, and in a deployed configuration, the distal end of the braided conductive member is retracted to invert the braided conductive member.
